C.3.25. Changements de la version 4.0.1 (23 décembre 2001)

  • Added system command to mysql.

  • Fixed bug when HANDLER was used with some unsupported table type.

  • mysqldump now puts ALTER TABLE tbl_name DISABLE KEYS and ALTER TABLE tbl_name ENABLE KEYS in the sql dump.

  • Added mysql_fix_extensions script.

  • Fixed stack overrun problem with LOAD DATA FROM MASTER on OSF/1.

  • Fixed shutdown problem on HP-UX.

  • Added DES_ENCRYPT() and DES_DECRYPT() functions.

  • Added FLUSH DES_KEY_FILE statement.

  • Added --des-key-file option to mysqld.

  • HEX(string) now returns the characters in string converted to hexadecimal.

  • Fixed problem with GRANT when using lower_case_table_names=1.

  • Changed SELECT ... IN SHARE MODE to SELECT ... LOCK IN SHARE MODE (as in MySQL 3.23).

  • A new query cache to cache results from identical SELECT queries.

  • Fixed core dump bug on 64-bit machines when it got an incorrect communication packet.

  • MATCH ... AGAINST(... IN BOOLEAN MODE) can now work without FULLTEXT index.

  • Fixed slave to replicate from 3.23 master.

  • Miscellaneous replication fixes/cleanup.

  • Got shutdown to work on Mac OS X.

  • Added myisam/ft_dump utility for low-level inspection of FULLTEXT indexes.

  • Fixed bug in DELETE ... WHERE ... MATCH ....

  • Added support for MATCH ... AGAINST(... IN BOOLEAN MODE). Note: you must rebuild your tables with ALTER TABLE tablename TYPE=MyISAM to be able to use boolean full-text search.

  • LOCATE() and INSTR() are now case-sensitive if either argument is a binary string.

  • Changed RAND() initialization so that RAND(N) and RAND(N+1) are more distinct.

  • Fixed core dump bug in UPDATE ... ORDER BY.

  • In 3.23, INSERT INTO ... SELECT always had IGNORE enabled. Now MySQL will stop (and possibly roll back) by default in case of an error unless you specify IGNORE.

  • Ignore DATA DIRECTORY and INDEX DIRECTORY directives on Windows.

  • Added boolean full-text search code. It should be considered early alpha.

  • Extended MODIFY and CHANGE in ALTER TABLE to accept the FIRST and AFTER keywords.

  • Indexes are now used with ORDER BY on a whole InnoDB table.
